Abstract
A three-dimensional object is made by repeating a process. An optical beam is irradiated on a predetermined portion of a powdery layer to form a sintered layer. A new powdery layer is formed on a surface of the sintered layer. An optical beam is irradiated on a predetermined portion of the new powdery layer to form a new sintered layer united with the underlying sintered layer. Because a portion of the sintered layer that is higher than a predetermined level is removed as occasion demands, the abnormally sintered portion on the sintered layer can be removed, making it possible to prevent stoppage of the shaping process, which may be caused by the abnormally sintered portion.
